Specification of Letters Patent.

Application filed June 11, 1913. Serial No. 773,048.

To all whom it may concern:

Be it known that I, JoHAN OLsEN YGAARD, a subject of the King of Norway, residing at Underhaugsveien 1, Christiania,

orway, have invented certain new and useful Improvements in Press-Studs Fastenings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

In press studs serving to hold together garments such as blouses, etc., two chief properties are required, firstly that they should not open by themselves and secondly that a long row of studs or buttons may easily be opened bya single pull. The press studs hitherto known do not satisfy these combined requirements.

To meet these two requirements in a perfect manner the lower part of the stud fastening device according to the present invention is attached to the garment in a special manner, the three or more fastening points being so arranged that the stud or head will have an eccentric position with respect to said points and nearer to the edge of the garment. It is also useful to bend upwardly the portion of the foot plate of the stud'which is remote from the edge.

In the drawings some embodiments of the invention are illustrated.

Figure 1 represents the lower part of the stud fastening in side elevation, Figs. 2, 3, 4 being plan views of various adaptations.

According to Fig. 2 the usual circular shape of the flat foot plate a has been kept; the three holes 6 for fastening the plate are symmetrically disposed, while the stud or head 0 has an eccentric position with respect to these holes and nearer to that edge of the plate which is adjacent to the edge cl of the garment. According to Fig. 3 the flat plate is oval and provided with five holes 6 According to Fig. 4c the flat plate is substantially circular but is provided at the portion remote from the edge d with an extension or tongue 6 which can be sewn to the fabric.

By placing the same part of each foot plate in the same relative position to the edge of the garment, a plurality of studs will be brought into alinement, and owing to the eccentric position of the stud in relation to the eyelets, one of the eyelets will be positioned at the greatest distance from the edge of the garment. The greater this distance, the greater will be the resistance against tilting of the stud on an axis parallel to the edge of the garment when a lateral pull is exerted on the two connected parts of the garment in the plane of the latter. The symmetrical disposition of the eyelets will cause two of said eyelets to be in a line parallel to the edge of the garment and substantially in alinement with the studs. This will prevent the studs from rocking on axis at right angles to the edge of the garment and this prevention will facilitate the separation of the socket member of the fastener, which is on the outside portion of the garment, from the stud when a pull is exerted on the edges of the garment in a direction perpendicular to the plane of the garment.

I claim:

1. A stud member for snap fasteners in which the socket member engages the stud only comprising a fiat metal circular base plate having three or more fastening points, and a stud for frictional engagement with a socket member and arranged eccentrically to said points and the axis of the plate, for the purpose specified.

stud member for snap fasteners in which the socket member engages the stud only comprising a flat metal circular base plate having three or more eyelets symmetrically disposed near its edge, and a stud adapted to frictionally engage a socket member and arranged eccentrically to said eyelets, one of said eyelets arranged at the greatest distance from the edge of the fabric to which the plate is connected and two of the eyelets arranged in substantially the same line as the stud with relation to the edge of the fabric, for the'purpose specified.

3. A stud member for snap fasteners in which the socket member engages the stud only, comprising a fiat circular base plate having three or more eyelets symmetrically disposed near its edge for securing the base to a fabric or the like, and a stud having a substantially spherical head adapted to frictionally engage a socket member and arranged eccentrically to the edge of the plate and the eyelets, whereby the distance between the stud and one of the eyelets isincreased Withoutincreasing the diameter of the plate, thereby increasing the resistance In testimony that I claim the foregoing as my lnvention, I have signed my name 1n presence of two subscribing Witnesses.
